In this short video I compare the new 200 Mbps 10 bit 420 internal codec with Prores 422 HQ from the Ninja V.
The file size difference is huge (4 vs 35 GB) so can you see the difference?
I can't but of course the 422 ProRes HQ file can withstand extreme editing better.
Yet unless you are doing extensive edits with the new codec there is no need for external recorders but you still need a monitor as the LCD is now smaller
